Auto-Protect blocking threats when on and offline every 5mins- virus checker not picking them up

Hi there.

 

For the past 4 days my Norton auto-protect has been popping up every 5 mins warning me that it is detecting threats, then blocking them. This happens even when offline so I'm worried there is a file or something buried within my files.

 

The threats are: when logging in: 'ZeroAccess P2P'

 

Then every 5 mins they are:  ZeroAccess B and C and Trojan Gen 2 and Gen 3

 

I've used the full system scan and the Norton Power Eraser but both return 0 threats (apart from removing tracking cookies)

 

This seemed to start after I transferred pics from my phone to my pc but have done this in the past and it has never caused problems before.

 

Having read up a little on what the ZeroAccess P2P, ZeroAccess Trojan B and C, and Trojan.Gen.2 and Gen.3 I'm concerned.

 

So far it says that Norton is blocking all the attempts for them to 'attack' but I'm not sure that's the case- especially since these attacks come even when I'm disconnected from the internet. 

 

Can anyone help? Thanks in advance.

 

I'm running a Windows 7 Home Premium 64 bit OS.

 

 

NOTEBACK- within the last 30 minutes, a lot of the security threats in my 'history' have gone from being 'Blocked' to 'Pending'. Should this be a worry? Can I take any extra measures to help? Thanks again.
